A Non-Shedding Fruit <i>Elaeis oleifera</i> Palm Reveals Perturbations to Hormone Signaling, ROS Homeostasis, and Hemicellulose Metabolism

The developmentally programmed loss of a plant organ is called abscission. This process is characterized by the ultimate separation of adjacent cells in the abscission zone (AZ). The discovery of an American oil palm (<i>Elaeis oleifera</i>) variant that does not shed its has allowed for...
